Does anyone leave their amp and preamp on all the time?

I listen most nights after work. I find that the system takes a while to warm up and sounds it's best if it has been shut off. So I leave it on. I always have and this is vintage stuff. The amp is a 25/25 Bedini class A. It stays warm but never hot. It has never caused an issue but recently I've been speaking with others that were stunned that I would do this. So let me know if I'm the only one that lets it run. Do you shut off the equipment after each session?

  Eddie,   S.S. i leave on all the time  It's the same as a light bulb.  You only see them go when you turn on a light.   Same with SS.  i know you have a very nice
 Power condishner.   Yes
 If not just blow as much money as you can on one
  You will want to buy me
Cocktails after doing it 
  The  power Condishner 
 Has to be over $1000  
   Just    Saying

I notice my Audio Research tubed line-level preamps (LS-15 and LS-16) keep the tubes glowing even when turned off; I believe this not only offers better sound sooner but also extends the life of the tubes. (I don't know about tubed amps, however.) I leave the big Levinson in stand-by in our main system. In our bedroom system I turn everything off when not in use. Ditto for our office system.

Love the Bedini amp!

I can't leave my Class A amps on all the time. They draw around 400 watts each just sitting there when not converting any of it to sound and they heat the room up noticeably by the end of a listening session.
They do not take long to sound good once turned on, though.

Similarly I do not leave my tube amp (main system) on as the tubes only have a certain life time and I intend to use it all with me in the room.

My main system preamp is also tube, but is always powered and just takes a minute or a bit better to wake the tubes up when switched to active mode. No big changes in sound once they are on.

All of the time. My Threshold T2 preamp doesn't have an on off switch so I have no choice. My Threshold amp has been left on for years and only gets a little warm and never hot, surprising for a class A amp.

I am sporadic with when my system is on or off during the week, but I typically leave my entire system on from Thursday night through Sunday night for weekend listening. During the week if I want to listen I’ll turn them on when I get home, but turn them off at the end of the night to save on power (class A baby!) and save the tubes. If I’m leaving for a few days or more I’ll turn the breakers off (they are dedicated to audio).
